Re: [Bug-apl] OpenBSD + GNU APL 1.8: Segfault immediately on apl startup

[Dr. Brian Callahan]

Hi Jürgen --

Sure. This is the output:
++ constructing DynamicObject::all_values
++ constructing DynamicObject::all_index_exprs
++ constructing Workspace::the_workspace
++ constructing StateIndicator::top_level_error
++ constructing Parallel::all_CPUs
++ constructing Macro::all_macros
Segmentation fault (core dumped)

Hi Brian,

thanks for reporting this. It looks like something goes wrong in the order of initialization
of static class members.

Could you please change line 35 of file src/static_Objects to read:

bool static_Objects::show_constructors = true;

and recompile and run GNU APL again? It will crash again but
the output before that is relevant (no stackdump needed).

The segfault is somewhat obscure because cerr << endl fails, but
this happens inside an assertion that should not trigger in the first place.

Best Regards,
Jürgen

Hi list --

I am in the process of updating the OpenBSD package of GNU APL to 1.8. It builds ok, but segfaults immediately upon running the apl binary.

There is a (unfortunately very large) gdb backtrace attached to this email. It seems to be a problem with the custom COUT/CERR handling but I'm not well-versed in GNU APL internals.

Happy to test out any patches.
